39 Class implementing StarDictReader interface and handling reading from compressed
40 files like .gz or .dz, using zlib
42 class CompressedReader : public StarDictReader
46 CompressedReader(QObject *parent = 0);
48 //! Creates new compressed reader and open file with passed filename
49 CompressedReader(QString filename, QObject *parent = 0);
51 //! Destructs object and closing file
55 Reads translations text from compressed dict file.
56 \param offset 64-bit offset of translation in uncompressed file, readed
58 \param len length of uncompressed translation, readed from idx file too
60 QByteArray readString(qint64 offset, qint32 len);
63 Reads 32-bits integer value from compressed file and convert it from
64 BigEndian to Little Endian
66 qint32 readInt32BigEndian();
69 Reads 64-bits integer value from compressed file and convert it from
70 BigEndian to Little Endian
72 qint64 readInt64BigEndian();
75 Reads single string from compressed file, end of string is marked as '\0'
78 QString readKeyword();
87 \returns true if file is opened or false otherwise
89 bool open(QString file);
91 //! Reads single char from compressed.
